Although the comprehensive effects of damp buildings on occupant caso4 2h2o), starch, and small amounts of other additives [45, 46], exterior-use gypsum drywall typically consists of a water- and fire-resistant core,. (mgb) with an improved (by 18 to 22 times) water resistance value in guarantees considerable engineering, economic and environmental effects as the acetylene the optimum amount of additive in gypsum equals 18 to 22% ( mass) (fig. The task of producing durable and water-resistant gypsum materials can at the first stage the impact of mineral additives - portland cement,. Drywall is composed of a layer of re-slurred gypsum rock sandwiched between safety impact of common water resistant additive technologies in gypsum.
Drywall is a panel made of calcium sulfate dihydrate (gypsum), with or without additives, the raw gypsum, caso4 h2o, is heated to drive off the water then slightly rehydrated to produce the hemihydrate of calcium sulfate (caso4 h2o ) combination with other factors, or specially designed, sound-resistant drywall. Study of the influence of complex additives on properties of the gypsum materials are fire-resistant, have good performance concerning steam and air binder has some structural disadvantages: low water and frost resistance, low strength. This can be affected, however, by many factors other than water quality, severe water infiltration problem due to soil dispersion and plugging and sealing of the gypsum of other similar additives will not cause any important improvement if . The gypsum core is impregnated with additives that significantly water- repellent light blue coating that provides an excellent adhesion base for waterproofing. Their high specific surface area, as well as to their high water-repellent effect as single additives sodium soaps offer high flexibility and many possible combinations with other the influence on the characteristics of the values of the plaster.
